Watch Graeme McDowell hit Kevin Kisner's mom with an errant tee shot

Graeme McDowell got a lucky break when his errant tee shot on No. 7 during the final round of the RSM Classic hit off a fan's ankle and bounced back into the fairway. It wasn't as lucky for the Kisner family.

For one, it didn't help Kevin Kisner, who G-Mac -- and the rest of the field -- is chasing. And it also hurt Mrs. Kisner. Literally.

Christy Kisner, who is at Sea Island hoping to see her son win his first PGA Tour title, was the unlucky fan who got hit.
